Stagnation Temperature Effect on the Prandtl Meyer Function

The Prandtl Meyer (PM) function plays a significant role in the supersonic flows calculation. To design a supersonic nozzle giving a uniform and parallel flow at the exit section [1-3], it is necessary to deviate the nozzle at the throat of an initial expansion angle to have the desired exit Mach number. Zebbiche features the new Prandtl Meyer function form, presented by integration of a complex analytical function, where the analytical calculation procedure is impossible. The interest then is oriented to the determination of the approximate numerical solutions. [PUBLICATION ABSTRACT]
